To alt whom it may concern.-

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States,residing at Hart ford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in-Mechanical Movements, of which the following is a specification.

This invention relates to mechanism for to starting the rotation aboutits axis of a wheel having a continuous orbital movement such, forinstance, as a type-wheel-for continuing such rotation and for stoppingthe rotation of the wheel at a determinate point in the pathof itsorbital movement, which mechanism is especially adapted for use inconnection with a certain class of key-operative mechanism-such, forinstance, as that described in my application Serial No. 41,521, filedDecember 29th, 1900.

In the drawin s accompanying the present specification an which setforth an embodiment of my present improvements, Figure 1 is a plan viewof such a mechanism. Fig. 2 is a vertical section of the mechanism, partbeing shown in elevation. Fig.3 is a sectional elevation of a portion ofthe mechanism shown in Fig. 2. Fig. 4 is a'plan view exhibiting therelation existing between the inter- 0 mittently-driven member and itsdriver dur-' ing the continuous orbital movement of the former. Fig. 5is mainly a sectional view drawn upon a somewhat larger scale, settingforth in detail the construction of the latch 3 5 mechanism embodied inthe present invention and showing the relation of the latch orgear-starter thereof, when projected, to the part with which it isdesigned to co-operate. Fig. 6 is a view similar to Fig. 5, butrepresents the latch as having beenpush'dinward and set. Fi 7 is a viewsimilar to Fig. 6, showing the Tatch in its normal position, also thekey for releasingit; Fig. 8 is a view similar to Fig. 7, showing theposition of the )arts immediately prior to the release of the latch, aposition occasioned by a slight depression of thekey. Fig. 9 is across-sectional view on the plane of the line aa in Fig. 6, looking-inthe direction of'the arrow.

Similar characters of reference designate corresponding parts in allfigures.

The present invention comprises means for carrying a rotatable wheel inan orbital or closed circuit path, combined with a device for initiatingthe rotation of such wheel at a given point in the path of its orbitalmovement, and devices brought into operation by the initiation of suchrotary movement where by the lattermovemcnt is continued to a [givenpoint in the orbit at which point the rotary motion is caused to cease.

' The mechanism embraced in the present invention is particularlyapplicable to powerdriven typewriters a type-wheel driven from therotatingwheel operating at a fixed point in its orbital movement to makean impression. wheel caused to operate is determined by "the amountof'rotary movement given to the wheel, which in turn is dependent uponthe point in the path ol'orbital movement at which the said wheel isstarted rotating.

The carrier for supporting the rotatable wheel is of suitableconstruction, and is adapted, as above stated, to move the same througha closed circuit path, and I find it convenient, and have so representedthe carrier in the present drawings, tomake the same in the form of arotary carrieror turret designed for continuous rotation about a fixedaxis. The turret, designated in a general way in the presentspecification and The particular die upon the typepriate form andconstruction. This framework in the present instance embodies abase-plate 2, which may constitute a part of the main framing of thetypewriter mechanism with which the present invention is combined, or itmay form a subordinate part of that framework.

As mounted in the present case, a stud 3 is ri idly secured to theframework, about which stud the turret rotates, a convenient device fordriving the same consisting of a driving-shaft 4 extending through thestud, which is made hollow for this purpose and connected at one endwith a driver and at the other end 'with the turret. Suitable 5 meansare rovide'd for actuating this drivlug-shaft, t at herein indicated ina conventional way consisting of a pulley 5 adapted to be driven from anconvenient source of power and rotating a out an extension 3 of 1 o thestud, the pulley being connected with the driving-shaft 4 by a collar 6,secured, for instance, by a pin 7 to the latter. Preferably theconnection of this pulley with the driving-shaft will not be a rigid onethe better to i5 prevent strains from being transmitted to the latter.The connection shown for this purpose consists of a pin 8 extending fromthe collar 6 into a slot of the driving-pulley having a widthsubstantially the same as that of the pin whereby there may be a slightaxial adjusting movement of the pulley permitted. Similarly, theconnection of the driving-shaft with the turret may consist of a pin 9extending from a collar 10 on 2 5 the driving-shaft and located in aslot '11 in the turret; A's.= thus constructed, the weight of the pulleyand connected parts is taken by the collar 10, which bears upon the uper end of the stud 3 while the end thrust o the go turret is receivedon a shoulder 12 of the stud.v It is evident from anexamination of Fig.2'that the construction allows a slight endwise lay of the parts to takeplace, by reason of the fact thatthe pin 9 is .not nor- 3 5 mally incontact with the bottom of theslot 11, thereby obviating theircrampingcven though the ends of the driving shaft be drawn slightlytogether when under torsion. lThe present turret construction embodies40 heads 13, 13 connected with each other by a sleeve or body portion14. The driven member is conveniently made in the form of a ear-Wheel,and it is designated genera ly erein by B. It is mounted for rotationupon the turret and for this purpose is provided with a shaft 1)journaled in the heads Among the purposes for which the presentinvention is applicable is that of imparting a rotary movement to arevolving type-wheel whereby an impression device thereon may be broughtinto the impression-for]ping point and caused to roll over and make animpression upon the surface of paper or i other substance locatedthereat, and l have indicated by dotted lines and in a general way,therefore, a type-wheel 14 secured. to

the u perend of the shaft 1).

diiverv for imparting a rotary movement to the driven member during thecontinuous orbital movement thereof, at the will of the operator, isconveniently made, in the form of an internal gear, designatedgenerallybj.

C. Normally, this driving member is inoperative to effect the rotarymovement of the in correct.

driven member, but becomes effective for that purpose upon theinitiation of the ro-' tary movement'of the latter under the control ofthe operator, as will be more fully set forth hereafter. wheel B formingthe driven member is normally out of engagement with. "the drivingmember, but upon the initiation of its rotary movement it is moved intoengagement. therewith. 7 5 As the present mechanism is designed tooperate at a considerable velocity, [have provided in order" to securesafety from breakage in case the driven member be im:

properly operated in the starting of it, or if the same. does not comeinto alinement with the teeth of the driven member when moved to aposition to engage therewith, a mounting for the teeth constituting thedriven 1 member which will permit the same to yield 8 5 slightly. Thisconstruction, as set forth, embodies a sprin l5 encircling the shank 16'of each tooth 16 inserted in an opening in a suitable gear-block 17 andexerting a pressure between a shoulder on the tooth and a plug 18closing the outer end of .the tooth opening through a bearing 'in whichthe stem of the tooth isadapted to slide. These teeth forming thedriving member are arranged concentrically about the axis of rotation ofthe tur-' 9 5 ret, and it is evident from the construction I that whenthe driven member is shifted to 7 bring the teeth of the same intovmeshwith the teeth of the driving member the latter may yield somewhatshould the alinement be A stop 19 at the forward end of each toothlimits its forward movement. This feature is claimed in my eopendiugapplica-tion referred to in the first paragraph of this description. 7While the turret'is rotating and the driven member B is inoperative, arecessed portion "of the periphery of the latter or a portion from whichthe teeth are omitted lies adjacent to and out of contact with the teethof the driving-gear, and it may be here stated that to effect theengagement of the two members the driven member adapted to be shiftedaxially. As the driven member is in the present case adapted to havemore than. I 1 one revolution the omission of the teeth from the portionwhich normally travels adjacent to the driving member is supplied by atoothed segment 20 arranged above the plane of the driving-teeth, but'insuch a position 2e that when the driven member is shifted axially toeffect engagement the segment comes into the plane of the drivingmember; thus the driven member acts in this position as a complete"gearhaving its full complement of teeth. This segment 20 may be formed, asin the present case, as an integral part of the driven member B, or theteeth may be IIO Such being the rela-- That is to say, the gear- 70'ment with the driving member C.

' vided with a resetting heel 21, which, in

tion of the parts of the ear wheel B, it may by a partial rotation berought lnto erigagfit e turret T, be then rotated, an orbital androtative movement will be given to the gear wheel and to the membersrotated thereby. A

which ma be communicated while said wheel is being rotated byits longerteeth, will move said wheel to a position where all of its teeth willbecome engageable with the teeth of' the drivingmember-C, in whichposition the gear wheel may be completely rotated by the driving member0. The gear-wheel B, may, moreover, be made in two parts, one being anordinary toothed wheel and the other a so-called mutilated wheel.

For initiating the rotary movement of the driven memberv and its shaft,there is provided in the present construction a startingarm21 similar tothe starting-arm described in PatentNo. 401,371, dated April 16, 1889,to which reference maybe made for a more par- 1 ticular descri tion ofits construction and operation. Su ce it here to say that it is procombination with a finger portion 21", op crates by a toggling action toreset the gear starter substantially in the manner set forth in thepatent referred tov When the shaft 12 is started rotating by theengagement of the gear-starter or latch with the starting-arm 2] ashifting device. isbrought into operation to effect the axial movementof the driven member. This device in the present construction consistsof an actuating or cam member 22 rigid with the shaft 1) and acooperating member 23, herein shown as consistingof a suitably-formedrecessed portion on the under surface of the lower head 13 of theturret.lVhen, therefore, the shaft is started rotating the actuating or cammember 22 rides out of the recess forming the member 23, therebyshifting the shaft into a position iii-which the driven member isbrought into enga ement with the teeth of the driving mem er. For thepurpose of retaining the various axially-movable parts in their twopositions corresponding to the normal or inoperative position of thedriven member and its operative position there is provided in thisinstance a suitable detent device, which, while exerting sufficientforce to retain the parts in their two positions, yet yields to permittheir movement under the action of the shifting members. This detentdevice as herein constructed consists of a spring-fmger 24 secured tothe upper head 13 of the turret and having its detent or end portion 24adapted to co-operate with a suitably-formed disk or flange 25 upon theturret shaft. Preferably the co-operating surfaces will be in clined, asshown, which will materially assist in the final positioning ofthe/parts endwise when such endwise movement iscommenced.

roper axial shifting of the 'gearwheeh Assuming that the rotary movementof the shaft 6 and attached type-wheel has commenced and an impressiondevice on the wheel has operated at the impression-forming point, itthen becomes necessary to shift the parts axially in the opposite direct on to disengage the driven member. The device provided in the presentconstruction for the urpose consists of a cam-plate 26 convenientlyaffixed to the gear-block 17 and having an inclined face 26 with whichcoacts a cooperating or cam arm 27 extending from the shaft b and, asthe shaft is forcibly rotated, sliding over the inclined surface andupward thereon, operating thus to carryt'hc shaft and attached partsaxially and move the driven member out of engagement with the driver.The final positioning of the parts is assisted b y the action of thedetent 24, and

the parts are caused to assume a definite final position by the cam 22,which seats itself in the recess of the member 23. The movement of theshaft endwise and the action of the detent 24 in effecting the finalaxial movement may be assured by a fixture located at such a portion ofthe mechanism as to be under the shaft 5 when the smooth-or toothlessportion of thedriven member arrives opposite the driving teeth, a devicefor this purpose being shown in the present in stance and consisting ofa block 26 secured to the base-plate 2 and having an upwardly extendingportion terminating adjacent to the lower end of the shaft 1).

If the mechanical movement is applied to 4 a typewriting-machine, asuitable feed-actu atingmechanism for imparting motion to the carriageof the typewriter may consist of a star-wheel 27 journaled in thebase-plate 2 in a position in whichits armsare adapted to move acrossthe axis of the shaft 1).. When the shaft is in its raised orinoperative position, the lower end bis raised above the plane of thestar-wheel and the latter is not affected by the continued rotation ofthe turret. \Vhen, however, the'shaft has been depressed, the endextends below the upper surface of the star-Wheel and during the rotarymovement of the turret co-operates with the successive arms of thestar-wheel to im- 1 part an intermittent rotary movement to that wheel,which may be prbvided with a pinion 28 serving asa driver for the feedmechanism ofthe typewriter.

It is evident that the amount of rotary movement im arted to theshaft 1) and hence to the type-w ieel attached thereto, will depend uponthe arc distance intervening between the impression point and that atwhich the rotary movement of the type-wheel is commenced. This distancemay be .made such as to suffice for an amount of rotary movement of'thetype-wheel that will result in a particular type or impres soin devicebeing presented at the impression point when I pose of initiating thisrotary movement there may be combined with the starting-arm aforesaid asuitable bolt or latch which upon its projectioninto the ath of the armas the samcis swung around y the rotation of the turret elfects therotary movement of the shaft to which the starting-arm is attached inamanner set forth in the previously-mentioned patent. Any suitablemechanism for the purpose may be employed for that particular latchmechanism embodied in the present invention. Proceeding now to adescription of this latter latch mechanism, I have shown but one suchmechanism located at a point outside of the circle of movement of theshaft 1), which will effect a definite amount of rotation from thispoint to the impression point. It is evident, however, that a number ofthe same may be employed located at different points and resulting indifferent amounts of rotation of the driven member. 1f a single latchmechanism is employed it (the supporting frame) may be as shownconsisting of a block M secured to the baseplate 2 and having an opening23 in which the latch 29 is located and through which it is adapted tomove into a position in which its inner end extends into the path ofmovement of the startingarm. 'The latch 29, whatever its cross-sectionalform, is journaled at its forward end in a bearing formed in the presentinstance in a plug 30 secured in the end of the latch recess, and it isprovided with a flange 31 whose forward side forms a shouldercooperating with the plug 30 to limit the outward movement of the latch.The latch is also provided with two catches set one in advance of theother, and the controlling escapement is similarly provided with twocatches arranged to be successively engaged by those ofthe latch. Thecatches on one of said parts are so constructed and arranged that onecfthem will sooner than'the other engage its corresponding catch so thatwhen such result happens the one so caught may be disengaged and thelatch remain hooked back by the other pair of catches, until these arein due succession also disengaged and the latch projected. That is tosay, the latch is provided with a catch 32 arranged forwardly of thecatch 33, with which catches are adapted to co-operate correspondingcatches 34, 35 upon the escapement E.

The forward side of catch 33 is beveled, as likewise the surface of theco-opcrating escapement catch 34, while the rearward side of the catch33 on the latch is also preferably beveled or inclined. The cscapenientE is supported by a ful('1'1n-s pport F provided with opposite andrcarwardly-cxtending sidepieces 36, 36 connected at their forward ends"by a cross-piece 37 provided with a pivotal portion 38, which isadapted to fit into a recess 39 formed in the bore of the latch opening.To the rearwardly-extending side-pieces of the fulcrum support theescapementis fulcrumed, cars 40, 40 being provided on the escapement forthis purpose. A spring 41 lo cated between and bearing against theflange 31 on the latch and the cross-piece 37 of the by the actu ationof the escapement.

It will be noticed, particularly in Fig. 7, which represents the normalor set position of the latch, that the cross-piece 37 of the fulcrumsupport is inclinedsomewhat to the axis of the latch, the pressure ofthe spring 'tending, therefore, to swing the fulcrum support about itspivotal connection in the latch opening and raise the escapement, theopening through the fulcrum support to permit the passage of the latchbeing somewhat enlarged to enable the fulcrum supportto assume thisrelative inclination. In this osilatch) the catch 34 bears against theenlarged portion at the rear of the catch 32 on the latch and swings theescapement about this enlarged portion as a fulcrum to raise and holdupward an operating-key whose and extending from the frame M. This keymay be provided with the usual markedfincatch 35 on the escapement andthe latch is projected outward by the actuating spring 41. Supposing,now, that the key remains depressed until after the latch has beenpressed inward by, the toggling action of the starting-arm, the catch onthe latch will engage with the catch 34, holding the latch in thisposition after the. starting-arm has left the Iatch,an-d preventing thusthe same latch from operating the startin -arin more than once duringthe rotation of the turret for any one depression of the key. When thekey is released by the removal ofthe finmovenicnt of the catch 33 on thelatch by the action of the spring 41 in'urging the outer end of thefulcrum support upward, releasing soon after the catch 34, which, asabove stated, has an inclined surface whereby this action isfacilitated. Upon the release of the catches 34 and 32 the latch movesoutward to a slight extent, contacting, however, with the catch 25,shown in Fig. 8, by which the latch is retained in its set positionuntil again actralod by the depression of the key.
